Definitions

  • the present invention relates to an optical disc recording and/or reproducing apparatus, and in particular to a technology of a list display of so-called thumbnail picture when conducting finalizing process, etc.
  • DVD-RAM digital versatile disc
  • the regulation of optical discs classifies DVDs into: a re-writable type, being represented by, such as DVD-RAM, on which information can be re-written or re-recorded; and a write-once type, being represented by, such as, DVD-R, on which it is difficult to re-write information if it was recorded once.
  • DVD-RAM as a representative one of such the re-writable media, recording and erasing can be conducted repeatedly, however the DVD-R, as the representative one of the write-once type media, has a feature that picture that was once recorded thereon cannot be erased easily.
  • the reproduction of the re-writable type DVD-RAM is able by only the reproducing apparatus corresponding thereto, however the write-once type DVD-R has a feature that it can be reproduced by means of a DVD player (i.e., the reproducing apparatus) that is widely available, if being conducted by the finalizing process is thereon. Therefore, the recording/reproducing apparatus being able to record on the DVD-R comes to increase in the number thereof.
  • thumbnail pictures each being a small-sized picture of a representative scene of the pictures inputted or recorded, are displayed on a monitor, in the form of a list, thereby improving the capacity of searching for an aimed picture.
  • displaying of the thumbnail pictures is called by “navigation (or navigation picture)”.
  • thumbnail data i.e., small-sized picture data
  • TOC Table Of Contents
  • the region on which the data are recorded can be discontinuous when the optical disc is of the re-writable type, therefore the system is so constructed that a region is prepared for recording the thumbnail data therein, thereby the thumbnail data can be recorded when recording. Also, even if there is no thumbnail data, it is possible to produce a list data of thumbnails by reading picture files into when reproducing, thereby to record them into the region for use of the thumbnail data. However, when the optical disc is of the write-once type, since the data to be recorded must be written into, sequentially and continuously, therefore the system is so constructed that the thumbnail data are not recorded in such the separate region.
  • the write-once type optical disc such as, DVD-R
  • DVD-R has a feature that it can be reproduced by a DVD player that is generally and widely used, if being conducted with a process at an end terminal of the writing, being so-called by “finalizing”.
  • finalizing As an operating method for conducting the finalizing process, it is common to select an item of the finalizing from a menu display, etc., thereby, conducting that process, in the process.

  • the thumbnail data cannot be recorded into the region separate from that of the recording picture data when recording, then no consideration was paid upon displaying a list of thumbnail pictures (i.e., the navi screen) in the write-once type optical disc. Therefore, because of no display of the list of thumbnail pictures (i.e., the navi screen) in the case of the write-once type optical disc, the contents thereof can confirm by only in the form of character information but not by themselves (i.e., not through the navi screen). For this reason, sometimes, it is impossible to jump to the picture that a user wishes to look at, therefore brings about a problem that it is inconvenient from a viewpoint of searching property thereof.
  • the user when the user tries to conduct the finalizing process on the write-once type optical disc before the finalizing process thereon, she/he can confirm only the number programs, recording time, remaining capacity, the number of markers, etc., but only through the character information, by the method of confirming the recording contents of the optical disc, therefore there is a problem that they cannot be confirmed by the pictures thereof.
